Dongba culture is the most representative part in the development of Naxi traditional culture and the treasure of China traditional culture. Dongba is a rare "living primitive hieroglyph" in the world at present. More than 20,000 Dongba classics written in this language are encyclopedias about the ancient social life and historical development of Naxi people.

Naxi language is generally classified as Yi branch of Tibeto-Burman family of Sino-Tibetan language family (some scholars believe that Naxi language is between Qiang branch and Yi branch). Naxi language is divided into two dialects: western dialect and eastern dialect. There are about 260,000 people using western dialects, accounting for 87% of the total population. The basic word order of Naxi language: subject-object-predicate. Generally speaking, Naxi people have two traditional scripts: Dongba and Goba. Dongba (Naxi hieroglyphics): It is a hieroglyphic with ideographic and phonetic components, and its writing form is more primitive than that of Oracle Bone Inscriptions. It is considered to be the only hieroglyphic in the world that still exists.

Dongba paper, the carrier of Dongba characters, was specially used to write Dongba characters in ancient Dongba. Its craft is purely a manual workshop, and only Dongba language from this workshop is original and charming. Dongba paper was invented and manufactured by Mr. He's ancestors 300 years ago. After losing 10 years, Mr. He resumed the production of Dongba paper, and developed a series of calligraphy and painting paper, mounting, high-grade business cards, embossed bookmarks, and grass-pressed live-face Tibetan scripture paper on the basis of tradition. Its exquisite texture and insect-proof characteristics are deeply loved by users at home and abroad. The raw material of Dongba paper is taken from the local unique plant material "Adada" and identified as Lijiang Daphne. Paper-making process consists of raw material collection, sun drying, soaking, cooking, water washing, retting, paper pouring, stickers, paper drying and other processes. The main tools are paper curtain, wooden frame, paper drying board, wooden mortar and so on. The movable paper curtain of Dongba paper is quite special, and the paper drying process is obviously influenced by the inverted paper method, with traces of papermaking method, which is the result of the compatibility of China papermaking method and India-Pakistan subcontinent papermaking method.
